OpenSea has been a vital part of the decentralised ecosystem because it was one of the first marketplaces for non-fungible tokens (NFTs). NFTs are proof-of-ownership tokens for digital assets such as artworks, in-game items, etc.
A marketplace where anyone can buy and sell NFTs is an excellent boon to the decentralised world. With new technology to buy and sell art, the artwork generally benefits from marketplaces like the OpenSea platform.
Step 1: Link your Metamask wallet to Opensea
Before buying your first dream NFT, you need to link your Metamask wallet to Opensea. If you have yet to create a MetaMask, you need to make yourself one today!
And then type in the URL https://opensea.io/. There is a little wallet icon at the top right corner. Click on it and you will see the wallet options that you can choose (Metamask wallet, Coinbase wallet). However, in this guide, I recommend you pick the Metamask Wallet ( the red fox icon ). Metamask is popular and easy to use.
There, OpenSea will prompt you to sign in to your MetaMask Wallet. Signing just confirms you are allowing the Dapp to interact with your wallet. It means you give authorisation for Opensea to connect to your Metamask wallet.
P/S: You have to make sure that the website you are signing in with your wallet is legit or not. In this case, make sure it is the official website of https://opensea.io/.
Step 2: Find your dreaming NFTs
You can easily find your NFTs by scrolling down. They have different categories that you can look at, such as Notable Drops, Top collections, Trending. They have several NFT collections to look for. Click the one that impresses you!
Step 3: How to buy NFTs on Opensea
Buy NFTs with Crypto Currency
OpenSea offers cross-blockchain support across Ethereum and Polygon. This guide briefly explains the differences between these various blockchains.
Buy NFTs with Etherium
Ethereum is a decentralized, open-source blockchain with smart contract functionality launched in 2015. Ether or ETH is the native cryptocurrency of the Ethereum blockchain. ETH is used to pay transaction fees (known as gas fees) on the Ethereum blockchain.
Make sure that you have enough Etherium for your NFT plus gas fees on your Metamask wallet. Gas fees is fluctuating between $40-$150 or even more depending on how busy the Etherium blockchain is. You also can check Etherium’s gas fees in real-time at https://crypto.com/defi/dashboard/gas-fees to reduce the extra payment.
Buy NFTs with Polygon
Polygon (previously known as the Matic Network) is a separate blockchain that provides scalable, secure and instant transactions with Ethereum currencies like ETH, USDC and DAI. Think of Polygon as a sibling to Ethereum, the currencies are similar, but the two blockchains have slight differences.
Beginning in July 2021, users can use Polygon to create, buy and sell NFTs without paying transaction fees, essentially creating a gas-free marketplace.
Buy your first NFT
After you find your beautiful NFT piece and see how much you need to purchase. Always prepare extra Etherium for the gas fees.
TIPS: Make sure you click on the one with the verified symbol. If that project doesn’t have a verified icon, you need to go and check their social media (twitter, discord, telegram) or even ask the development team for the official Link to Opensea. Scammers are everywhere. Be aware of!
Then click “Buy Now”.
If you have enough ETH in your wallet, you will be charged automatically. If you don’t you will be prompted to add more.
Buy NFTs with Credit Card
After you click “Buy Now”, you also can purchase that NFT with your credit card by click “Add Funds” then “Buy with card”. Remind that you only can deposit a maximum of $12,000 for a transaction.
Even if you purchase with a credit card, you will need a wallet to withdraw funds from Metamask. Make sure that you have Etherium for the gas fees.
Participate in an NFT Auction
You are not only can purchase NFT right away, but also you can join NFT Auction. You are able to see when that NFT sale will end so you can make the right decision. And now, click “Place Bid”. Your bidding needs to be higher than the previous person.
Step 4: Check your NFT
Go to “Profile” and you will see your purchased NFTs at “Collected”
